Rosecove Beach

Rosecove Beach is a beach connecting Route 8 and Rosecove City. Palm trees are located on this beach, which can be headbutted to battle wild Pokémon living inside of them.

Lighthouse
When the player first arrives in Rosecove Beach, Team Eclipse is once again causing trouble, wanting to rob the Blue Orb from an old man in the lighthouse. Eclipse Grunts are also scattered around the beach and Rosecove City, blocking access to Rosecove Gym. While Rival Jake distracts the grunts to let player proceed to the lighthouse, Eclipse Admin Gabe robs Blue Orb from the old man and threatens to summon another Legendary Pokemon Kyogre.

Upon defeating Admin Gabe, he throws the Blue Orb into the ocean and thus, activating it by accident. Kyogre is summoned and brings rainstorm to the city, but it doesn't act in Team Eclipse's favour, and blasts them off with Origin Pulse. Kyogre then returns Blue Orb to the old man, after he said that he thought only Team Rocket could blast off like that. His granddaughter Tess then joins the adventure along with Jake. Rosecove Gym is opened afterwards.

Battle Pier
The battle pier is where five trainers battle with players leading up to the boss of the battle pier. The boss gives you a King's Rock, which can cause flinching to the opposing Pokémon and make certain Pokémon evolve into their branch evolved forms if held when trading.

Trainers
Note: Trainers marked with a star symbol (*) can be rematched.

Items

 * King's Rock: Given by the boss of Batter Pier upon victory.
 * Protector: Given by grandfather of Tess after defeating the Eclipse Admin Gabe.

Trivia

 * Trainers in this beach, as well as in Rosecove Gym, are usually called "Beach Bums" (for male), and "Beach Babes" (for females).
 * Beach Babe Samantha -- the only trainer that can be rematched on Battle Pier, is currently the best spot for training the Speed of Pokemon, because her Staryu and Starmie give out 4 Speed Effort Values in total.
